Pretensioned: meaning, definitions and examples
🏗️
pretensioned
[ prɪˈtɛnʃənd ]
engineering term
Pretensioned refers to a method used in the construction of certain types of concrete elements, where tendons or cables are pre-stressed prior to any loads being applied. This process allows for greater strength and durability in bridges and buildings, as it helps to counteract tensile forces that lead to cracking. The tendons are stretched before the concrete is poured, and once it hardens, the tension is released, thus compressing the concrete internally. This technique creates a stronger structural element capable of withstanding higher loads than standard methods.
Synonyms
pre-stressed, stretched, tensioned
Examples of usage
- The pretensioned beams improved the building's stability.
- Engineer recommended using pretensioned cables for the bridge.
- Using pretensioned components reduced construction time significantly.

Etymology
The term 'pretensioned' finds its origins in the early developments of reinforced concrete techniques in the 20th century. As the demand for stronger and more efficient building materials grew, engineers began experimenting with various methods of pre-stressing concrete to enhance its performance. The concept of pre-tensioning involves applying tension to cables or rods before they are encased in concrete, leading to improved structural integrity and longevity. This practice became more widespread in the 1950s and 60s, particularly in the construction of bridges and large span structures. Over time, the evolution of materials and techniques has made pretensioned concrete a standard practice in modern engineering, significantly influencing the design and construction of numerous architectural landmarks around the world.
